Specification of Letters Patent. Application filed November 8, 1911. Serial NO. 659,188.

Patented June 4, 1912.

To all whom it may concern:

Be it knownthat I,.DAVID S. COLE, a citizen of the United States, residing at Washington, in the county of Washington and State of Iowa, have invented certain new.

and useful Improvements in Mailing-Tubes, of which the following is a specification, reference being had therein to the accompanying drawing. 4

This invention relates to improvements in mailing tube sheets or wrappers for articles which are to be sent by mail or express and 'especially'to wrappers or tubes which are adapted to be used in the transmission of drawings, photographs, light merchandise or other articles which can be conveniently rolled or folded into a small space. The present invention has particularly for its object the production of an efiicient roll wherein corrugated paper is used for greatly reinforcing the same and which is also provided with an additional sheet of paper for engaging the contents of the roll whereby the corrugations will not form any impression upon the article or papers to. be transmitted within the roll.

- Another object of this invention 'is the production of an efiicient means for transporting drawings, photographs, etc., which may lie out flat, and thereby make the same easy for arrangement in bulk. 1

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed. In the drawings :-Figure 1 is a perspective view of the'device showing the same in an unrolled condition. Fig. 2 is a perspective view of thewrapping device showing the same in a partially rolled condition. Fig. 3 is an end view of the wrapper showing the same ina. rolled condition. Fig. 4

is a side elevation of the wrapper showing the same in an unrolled position.

The invention comprises a mailing tube wherein the same is provided with a sheet 1 which carries at one end a corrugated sheet 2. The ordinary writing sheet 3 or article.

to be transported is placed upon the sheet 1 near its inner end as disclosedin' Fig. 1

to tl'le'qu'terend of the sheet 1 and the tube is then rolled, as is indicated in Figs. 2 and 3 of the drawings.

By rolling the end 1 containing the-corrugated sheet 2 as illustrated in Fig. 2 it will be obviousythat the plain sheet 1 will be rolled so as to engage the sheet 3 or sheet to be transported in the tube. In this way the corrugations 2 will not press directly upon the sheet or material to be transported but said sheet will be protected by means of the outer sheet 1. It will therefore be obvious that a very eflicient mailing tube has been produced for transporting drawings, such as those which are used by the Patent Oflice where it is necessary to have the drawings transported without injury to the same, and also t-hat'the same tube may be usedin .connection with valuable photographs without, fear of rumpling or crackof the drawing. A sealing flap is secured ing the same in transit. The desired result is obtained by first rolling the corrugated strip without engaging the sheet 3 and by sosrolling the corrugated strip it will be obviifus that an eflicient reinforced core will be rolled. It will'therefore be obvious that the portion of the sheet 1 whichis upon .the

back of the corrugations 2 will form a very eificient protector sheet.

What is claimed is A mailing tube comprising a plain backing sheet, a corrugated sheet secured wholly produced upon which the sheet 3 may be upon the inner end portion of said backing mailed, between said cylinder" and said protecting sheet, and a sealing sheet secured to the outer end fied. I

. In testimony whereof I hereunto affix my signature in presence of two witnesses.
